Hello
I had same Problem with Dell Latitude E6540 and I think it's the same Driver needed in Opt9020. The Driver package from Dell has actually a Problem (in Version A01). So I've downloaded the Network Driver directly from here (Intel Download Center). Extracted, I added the Driver of the following Folder: .\\PROWinx64\PRO1000\Winx64\NDIS63.
Kind regards
Chris
